VALVE.

SPECIFICATION forming pari'. of Letters Patent No. 667,267, datedFebruary 5, 1901.

Application filed April 27, 1897. Renewed June '7, 1900. Serial No.19,486. (No model.)

To all whom t 11i/ty concern:

Be it known that I, THEOPHIEL PAUL WAL- TER, a citizen of the UnitedStates, residing at Beatrice, in the county of Gage and State ofNebraska, have invented a new and useful Valve, of which the followingis a specification.

This invention relates to valves, and especially to that class of valvesemployed in con- Io nection with pneumatic tires for inflating anddeiiating the same.

Valves used in connection with pneumatic tires are generally of one ortwo classes, either what is termed as cot-valve, in which a metal tubeis employed for carrying or containing the valve and constituting a partof the valve shell or casing and which is inserted into the rubber cotor valve tube projecting from the tire and clamped therein by 2o abinding-wire wrapped around the cot and confining it upon or about themetal tube, or a shoe-valve, in which a like tube has an end flangewhich passes into the tire itself and an outer nut screwed on the metaltube z5 to clamp the tire between the nut and flange. In both types ofvalve the metal tube is known as the tire-tube and constitutes onemember of the valve-shell, to which the other member may be connected,so that the valve 3o proper may play between the two members.

In the present invention the tire-tube is employed as a mere carrier orhousing for the valve-shell and valve proper, a valve complete in itselfand comprising a valve shell or casing, valve proper, valve-stem, andvalveactuating means being coupled to the tiretube in such manner thatby a simple operation the said valve in its entirety may be removed fromthe tire-tube for repair, dre.

4o While the present invention accomplishes the advantages aboveenumerated, the construction of the valve as a whole is simple,inexpensive, and durable, and the parts are readily accessible, so thatany one may quickly disassociate the several parts of the valve, cleanor repair the same, and reassemble the parts without touching the rubbercot or disconnecting the tire-tube therefrom.

Other objects and advantages of the inven- 5o tion will appear in thecourse of the ensuing description.

The invention consists in a valve embodying certain novel features anddetails of construction and arrangement of parts, as hereinafter fullydescribed,illustrated in the drawings, and incorporated in the claims.

In the accompanying drawings, Figure lisa longitudinal section takenthrough a valvetube and tire-tube, showing a valve constructed inaccordance with this invention and held 6o therein. Fig. 2 is alongitudinal section through the tire-tube and union, the valve shell orcasing being shown in elevation. Fig.

3 is'an enlarged longitudinal section through the valve shell or casing.Fig. 4E is an en- 65 larged perspective view of the valve detached. Fig.5 is an enlarged cross sectional view through the valve. Fig. 6 is alongitudinal section through the tire-tube with the containing-valveshell in elevation, showing a 7o modification in the manner ofassociating said parts. A

In the drawings, l designates the valve-tube of a pneumatic tire,whichis pro vided with an enlarged base or head 2, adapted to be vulcanizedor otherwise connected to the tire itself, and 3 indicates thetire-tube, having one end open and its other end closed, With theexception of a central hole or perforation, forming an egress-duct,adapting it to com- 8o municate with the interior of the tire through anopening at the center of the head or base 2 of the valve-tube. Thetire-tube 3 is provided on its outer surface with a series of ribs orridges to permit it to be securely held within the valve tube or cot 1by means of a binding-wire 4, wrapped around the valve-tube in theordinary way.

5 indicates the valve shell or casing, also made in tubular form andhaving an eXteri- 9o orly-smooth cylindrical inner end adapted to beslidingly inserted in the hollow socket of the tire-tube through theopen upper end thereof, the shell 5 being formed eXteriorly of or beyondthe end of the tire-tube with an en- 95 larged outer end and having aprojecting shoulder or flange 6, extending around it, the under side ofwhich shoulder is recessed or provided with an annularvgroove to receivea packing-washer 7, of rubber, leather, or other roo suitable material,adapted to tit against the outer edge of the tire-tube, as clearly shownin the drawings, so as to form an air-tight joint between the parts atthis point. Fora similar purpose an annular washer 8 will by preferencebe arranged in the bottom of the socket of the tire-tube in position tobe engaged by the lower end of the valve shell or casing when the latteris inserted in the tiretube, as shown in Fig. 2.

Qindicates a union or coupling sleeve for holding the valvecasing andtire tube together, said sleeve having an inturned flange 10 formedaround it at or near its outer end and adapted to engage over theprojecting flange 6 of the valve-shell, the lower part of said sleevebeing internally screw-threaded,

to engage exterior threads on the upper part of the tire-tube, asclearly shown in the draw- 1ngs. l

In Fig. 6 I have shown the tire-tube 5 interiorly threaded, as at 20,and a valve-shell exteriorly threaded and screwed therein. By sucharrangement the coupling-sleeve 9 may be dispensed with and a simplerand cheaper connection between the tire-tube and valve shell or casingprovided.

The upper end of the valve-shell 5 is eXteriorly screw-threaded toreceive a cap 11, by means of which the outer end is closed, and whensaid cap is removed the interiorlythreaded portion of the casing whichprojects beyond the union 9 is adapted to receive a pump connectionforinl'lating the tire. The valve shell or casing is provided with apassage extending through it from end to end, and a diaphragm orpartition 12 extends across said passage,formingacontracted neck, andprovided with a central opening or perforation forming an ingress-duct,a valve 13 being arranged within said passage, which constitutes thevalve-cham ber. The construction of the valve is clearly illustrated inFig. 4 and is adapted to control the passage of air through thevalve-shell into the tire. The valve 13 has a stem 14, which is arrangedto play in the central opening in the partition or neck l2 and has itsupper end arranged adjacent to the mouth of the casing 5, so that it maybe conveniently pressed inward to unseat the valve in case the lattershould have a tendency to stick. The body portion of the valve istubular and is provided upon the outer side with air grooves or channels15, extending longitudinally thereof. The valvestem 14 is connected witha tubular body portion by means of a head or crown extending across thebody slightly Within the outer edge of the same, whereby an annular seator recess is formed in the upper end of the body, in which is adapted tobe held a Washer or Valve proper,16, of rubber or the like, adapted toengage a valve-seat formed by the under side of the partition 12 in thevalve-shell. The inner end of the valve is left open to receive avalfve-seating spring 17, the upper end of which is engaged by the heador crown by` which the stem or valve is secured to the body and theinner end of which is adapted to rest against a tubular plug 1S, screwedinto the lower end of the casing, with which plug the inner end of thetubular body of the valve is adapted to engage, for whichfreason saidinner end of the body is provided with notches to permit the passage ofthe air into the tire when the valve is unseated` By the arrangementsdescribed it will be seen that when it is desired to remove thevalvefrom the tire for the purpose of repairing or cleaning the same it isnot necessary to remove the tire-tube from the valve-tube of the tire,as is the case with the ordinary construction; but it is only necessaryto unscrew the union 9, after which the valve may be readily removedfrom the air-tube as one part. When the repairing or cleaning has beendone, the parts may be readily associated, and it will be seen that thespring is such as to permit a tight joint to be made between the partsno matter how many times they may be detached from each other.Furthermore, the construction of the valve itself is very simple andinexpensive, since, as will be evident, the spring is housed within thetubular body of the valve and is thus prevented from becoming compressedor set, so as to render the valve inoperative.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.
